SPECIFICATION forming part of Letters Patent No. 728,158, dated May 12, 1903. Original applicationfiled March 24, 1902, Serial No. 99,156. Divided and thisapplication filed July 28, 1902. Serial N0.117,379. (N0 model.)

To aZZ whom it may concern:

Be it known that we, OWEN BULLOCK, residing at Marlows, Hemel Hempstead, and WILLIAM HENRY FORTY, residing at The ford, England, engineers, subjects of the King of Great Britain, have invented certain new and useful Improvements in Shuttle-Motions for Looms, of which the following is a specification.

This invention relates to shuttle mechan= ism for looms in which the shuttles are passed to and fro by means of two pusher-rods,'one at one side of the loom, the other at the other.

According to this invention the shuttle is provided with a spring-clip at each end, and the rods are formed with oblong heads whichwhen turned into one position can pass into and out of the spring-clips without being caught by them,but when turned into another position can be pressed into the clips, but not drawn back from them. The pusher-rods are caused to be moved simultaneously toward one another, and then both of them are simultaneously drawn back to the sides of the loom. When the rods move toward one another, the head of one rod, which then pushes forward the shuttle in front of it, is in such a position that its head is not caught'by the spring-clip at that end of the shuttle which the rod acts against. lrVhen the shuttle has been thus pushed half-way across the loom by one rod, the spring-clip at the opposite end of the shuttle passes onto and catches the head of the other rod, and then when both rods are drawn back to the sides of the loom the shuttle is drawn along by this second rod and its movement across the loom thereby completed. At the completion of the shuttles movement a partial turn is given to both rods to reverse their action when the shuttle has to be passed across .the loom in the opposite direction.

In the drawings annexed we have shown shuttle mechanism constructed to act in the above manner applied to a loom for weaving coir mats. In this loom the mats are woven double, face to face, as has before'b'een proposed, and two shuttles are used, one forthe upper ground cloth and the other for the lower one.

Figurel is a plan view of so much of a loom having our improvements applied to it as is necessary for enabling the improvements to be fully understood. Fig. '2 isa longitudinal section of the front part of the loom on an enlarged scale. Fig. 3 is a front elevation of the'mec'hanism at one side of the loom for passing the] shuttles, the side of the loomframe beingin section. Fig. 4 is a plan view of one oftheshuttles and of portions of the two drivers by which it is moved to and fro. Otherparts of the loom besides those required for giving movement to the shuttles are shown in the drawings; but as these other parts .are described in another application for patent, Serial No. 99,756, made by us it is unnecessary to describe them in this specification.

In the drawings, A is a cam-shaft revolved continuously by gearing from the shaft A, driven from the driving-shaft A On it are cams for transmitting motion to various parts of the loom, as described in said other application for patent made by us, Serial No. 99,756. E is another shaft also receivinga continuous revolving movement from the shaft A. From the ends of the shaft E motion is given to the L shuttle-passing mechanism at each side of the loom, as hereinafter described.

. The mechanism for crossing the groundwarps of each' ground .fabric and for crossing thepile-warps may be arranged in any. ordinary way. Only the heddles F of this mechanism are shown. I

M represents the bladesof the reedor comb ofthe batten. The back ofeach of thetwo shuttles has upon it a T-head N, which can be slid to and fro through correspondingly-shaped notches in the front face of the blades M.

O O are the pusher-rods for passing the shuttles through the sheds in the two sets of ground-warps. The acting end of each rod is formed with a barbed head 0 of a width greater than its thickness and with a projecting flange 0 in rear of this head. Each end of the shuttle case is formed with a hole through it, through which the head 0 can pass freely, but not the flange 0 Inside each end of the shuttle-case are two spring-catches 0 The heads 0' of the pusherrods can when turned into one position pass freelyin either direction between the springcatches; but if a quarter-turn be given to the rod the spring-catches have to give way when the barbed head is pushed forward between them, and the barbed head cannot be withdrawn when drawn back in the opposite direction.

When a shuttle is at one side of the loom and is to be passed across to the opposite side, the flange O of a pusher comes against the end of the shuttle and pushes the shuttle halfway across the loom. Here its opposite end encounters the barbed end of another pusher,

which pushes aside the spring-catches O at that end of the shuttle, and the catches then close together in rear of the head. When the two pusher-rods are drawn back away from one another, this last pusher-rod draws the shuttle along with it, as the shuttle cannot escape from its head. The other pusher-rod, which before was pushing forward the sh nttle by its flange 0 can be drawn back freely, as its barbed head is in such a position that it can be drawn back freely without engaging with the catches 0 which are at that end of the shuttle. The last half of the movement of the shuttle is thus effected by the second pusher drawing it along with it, and a heavy tension can thus be maintained upon the weft for as long as may be required.

The pusher-rods are actuated in the following manner: The two pusher-rods at each side of the loom are at their outer ends both coupled to a slide P, which can be slid to and fro along fixed guide-rods Q. The connections between the pusher-rods and the slide are such that the pusher-rods can have a partial turn given to them, but are moved endwise when the slide is moved in either direction. The slide is moved to and fro by its being coupled to one end of a lever B, the opposite end of which can turn on a pivot R. (See Fig. 1.) In the arm is aslot R into which enters a crank pin R on a disk fixed to a vertical axis R so that the arm can be moved to and fro by giving one complete turn to this axis, and each time that the axis makes one complete turn the pusher-rods at the two sides of the loom are made to move inward across the loom toward one another and are then drawn back again. To give a complete turn to the axis R at the times when the movements have to be made, the axis R is geared with a second axis R upon which is a toothed wheel B. This toothed wheel is acted upon by pegs R which project out from a disk R on the shaft E, which receives a continuous revolving movement through gearing actuated from the driving-shaft of the loom. \Vhenever these pegs come around to act upon the toothed wheel R, they give a half-turn to this wheel, and this movement gives a complete turn to the axis R When both sets of pusher-rods have been drawn back into the position shown in Fig. 3, heads formed upon their outer ends enter and fit into sockets S (see Fig. 3) upon short axes S, which are in a line with them. The short axes S, which are in a line with the two pusher-rods at each side of the loom, are geared one with the other by toothed wheels S so that if a partial turn is given to one the other also has a partial turn given to it. To give to them this partial turn, one of them is made to gear with a toothed wheel S on an axis S (See Figs. 1 and 2.) On this axis is a lever S, the two arms of which are acted upon alternately by a pin S, projecting from one of the heddles F, used for raising and lowering the pile-warps, so that when this heddle is raised or lowered a quarter-turn is given to the axis S and so a quarter-turn is given to each pusher-rod. Thus after each outward movement of the pusher-rods each pusher-rod has a quarter-turn given to it, and the pusher rods which were drawing shuttles along with them are turned into a position in which their heads are free to disengage themselves from the shuttle, while the pusher-rods on the opposite side of the loom are turned into a position such that their heads will engage with the shuttles when the shuttles are pushed onto them.

What we claim is 1. The combination of the shuttle, the spring-catches on the opposite ends thereof, the pusher-rods on opposite sides of the loom in line with each other, the barbed heads on the pusher-rods adapted to engage the catches on the shuttle, the enlargements on the rods in rear of the heads, means for simultaneously moving the pusher-rods toward each other and for causing the shuttle carried by one of the rods to be transferred to and become locked with the other rod, means for then drawing back the rods, and means for giving a partial turn to the pusher-rods when their backward movement has been completed.

2. The combination of the pusher-rods O the slides P to which they are coupled, the lever-arms R to which the slides are coupled, the crank-pins R entering slots in these arms, the axes R* carrying these crank-pins, the axes R with which the axes R are geared, the pinions R fast on the axes R the pegs R acting on these pinions, the disks R to which they are fixed, the revolving shaft E which carries the disks, the sockets S with which the outerends of the pusher-rods engage when their backward movement has been completed, and means for then giving a been completed, and means for then giving partial rotation to these sockets. a partial rotation to these sockets. 3. The combination of the pusher-rods O, OWEN BULLOCK. means for moving them endwise toward and WILLIAM HENRY FORTY. 5 away from one another, the sockets S with Witnesses:
